The Adjustable Thread Cutterz Ring is a handy tool that you can take with you anywhere; they are even TSA allowed! These adjustable rings have a double-sided, stainless steel blade that is ideal for sewing, quilting, crafting, and jewelry making. The Thread Cutterz Rings are one size fits all thanks to the adjustable velcro straps. These Thread Cutterz Rings feature real Swarovski Crystals and are available in three colors; pink, black, and white. If you want more or less sparkle, Thread Cutterz also makes basic bands without jewels. Each ring is hand-finished in the USA.
